BACKGROUND Cryotherapy is a safe, affordable, and effective method of treatment for cervical intraepithelial neoplasia. In some low-resource settings, environmental conditions or qualities of the refrigerant gas can lead to blockage of cryotherapy equipment, terminating treatment. A prototype of a gas conditioner to prevent operational failure was designed, built, and field tested. METHODS Th...

Panthenol is the alcohol corresponding to pantothenic acid, with the formula HOCH 2 C(CH 3) 2 CHOHCONH(CH 2) 2 CH 2 OH. It is a member of the vitamin B complex (B 5) and a component of coenzyme A. Panthenol is produced synthetically from 2,4-dihydroxy-3,3-dimethylbutyric acid and b-alanine. Common sources are food products such as liver, kidney, yeast, crude molasses, whole grain cereals, milk ...

During a medical entomology course in Boa Vista, Roraima, colonies of Triatoma maculata closely associated with pigeon nests were observed in concrete air-conditioner box located on the external plastered and cemented walls of a modern brick-built apartment block. In only one eight-hole ceramic brick, located inside one air-conditioner box, 127 specimens of T. maculata were collected. T. macula...

In this paper, a uniformly elliptic second order boundary value problem in 2D is discretized by the p-version of the finite element method. An inexact Dirichlet-Dirichlet domain decomposition pre-conditioner for the system of linear algebraic equations is investigated. The ingredients of such a pre-conditioner are an pre-conditioner for the Schur complement, an preconditioner for the sub-domain...

BACKGROUND Despite widespread clinical uses of resin-modified glass-ionomers (RMGIs), their sealing ability is still a concern. This study evaluated the effect of delayed light activation (DLA) of RMGI on marginal sealing in differently pretreated cavities. MATERIALS AND METHODS In this in vitro study, two standardized Class V cavities were prepared on the buccal and lingual surfaces of 56 so...

background: denture stomatitis is a common oral lesion following the use of ill-fitting dentures. a layer of tissue conditioner is usually used to improve adaptation of the denture. these liners can support the in vivo adhesion and colonization of the oral candida . the aim of this study was to evaluate the efficacy of the two common antifungal agents mixed with tissue conditioner against candi...

in this study, the performance of a fabricated fluffer was evaluated and compared with common field curing methods for alfalfa. the drying rate, baling loss and alfalfa nutrient value (dry matter and crude protein) were the criteria for evaluation. the alfalfa was cut using a mower-conditioner. a randomized complete block experimental design was used with three treatments (fluffing swathed alfa...

Feedback is a very powerful concept and has numerous applications. Examples of feedback systems abound in everyday life. For example, the thermostat on an air conditioner unit uses feedback to maintain a comfortable temperature within a room. Similiarly, our bodies use feedback to increase antibodies to fight off an infection. By definition, feedback is the process of combining the output of a ...
